We divide 902155 by 3
Let's see how many times 3 fits into 902155.

On to step 1:
The number 3 fits into 9 3 times, leaving a remainder of 0.
Put 3 as the next digit of the answer. 
Result so far: 3.0
Deduct 9 from 9 and we're left with 0.
Take the next digit (0) from the dividend and append it to 0, then repeat: 0 / 3

Advancing to step 2:
3 goes into 0 0 times with a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 30.0
If we subtract 0 from 0, we get 0.
Fetch the next digit (2) from the dividend, attach it to 0 and continue: 2 / 3

On to step 3:
The number 3 fits into 2 0 times, leaving a remainder of 2.
Use 0 as the next digit of our solution. 
Result so far: 300.0
If we subtract 0 from 2, we get 2.
Grab the next digit (1) from the dividend, add it to 2, then carry on: 21 / 3

Let's proceed to step 4:
If we divide 21 by 3, we get 7 and a remainder of 0.
The number 7 becomes the next digit in our result. 
Result so far: 3007.0
Subtracting 21 from 21 leaves us with 0.
Bring next digit (5) of the dividend behind the 0 and repeat the process: 5 / 3

Step 5:
When dividing 5 by 3, we get 1 with a remainder of 2.
The next digit of our result is 1. 
Result so far: 30071.0
If we take 3 away from 5, we end up with 2.
Append the next digit (5) from the dividend to 2 and continue with: 25 / 3

Going ahead to step 6:
When dividing 25 by 3, we get 8 with a remainder of 1.
Record the quotient 8 as the next digit in the result. 
Result so far: 300718.0
The remainder is 1 after subtracting 24 from 25.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Step 7:
10 divided by 3 is 3 with a remainder of 1.
The number 3 becomes the next digit in our result. 
Result so far: 300718.3
The remainder is 1 after subtracting 9 from 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

On to step 8:
3 can be fit into 10 3 times, resulting in a remainder of 1.
The next digit of our result is 3. 
Result so far: 300718.33
If we take 9 away from 10, we end up with 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

In conclusion, the division gives 300718.33 with a balance of 0.001.
